Fluidra - Fan Speed Relay for Z400 iQ Heat Pump (R32)

Fluidra – Fan Speed Relay for Z400 iQ Heat Pump (R32)

This is the genuine Fluidra replacement fan speed relay for the Zodiac Z400 iQ pool heat pump range using R32 refrigerant. The relay acts as the electrically operated switch that controls the fan motor speed, enabling the heat pump’s control board to regulate airflow precisely across different operating modes — from normal heating to silent mode and active defrost cycles.

Compatibility

This relay is designed for the Fluidra Zodiac Z400 iQ TD7 S heat pump with R32 refrigerant. Always cross-reference the SKU against your unit’s wiring diagram or service manual before ordering, as the Z400 iQ range includes multiple variants (MD and TD series) that may use different components.

Why Genuine Matters

A faulty or incorrect fan speed relay can cause the fan to run at the wrong speed or fail entirely, leading to reduced heating efficiency, compressor stress, or unit shutdown. Using a genuine Fluidra part ensures the relay meets the exact electrical ratings specified for your heat pump’s control board, maintaining safe and reliable operation.

Installation

Replacement of the fan speed relay involves working inside the heat pump’s electrical enclosure and should be carried out by a qualified pool heating technician or refrigeration engineer. Ensure the unit is fully isolated from the mains supply before beginning any work.
